    <p>Here is a simple example of what you are looking for. What you need is <code>deepCopy</code> of the clicked <code>JLabel</code> and then retrieve it back and draw it to the <code>JPanel</code>.<br> <img src="https://i.stack.imgur.com/f8l7d.png" alt="enter image description here"><br></p> <pre><code>import javax.swing.*; import java.awt.event.*; import java.io.*; import java.awt.*; import javax.swing.border.*; class CopyLabel extends JFrame { JPanel panel ; JPanel centerPanel; int clickCount = 0; ByteArrayOutputStream baos; ByteArrayInputStream bins; public void createAndShowGUI() { setTitle("Copy JLabel"); JLabel label1 = new JLabel("JLabel1"); JLabel label2 = new JLabel("JLabel2"); panel = new JPanel(); label1.setForeground(Color.blue); label2.setForeground(Color.red); panel.add(label1); panel.add(label2); class MyMouseAdapter extends MouseAdapter { @Override public void mouseClicked(MouseEvent evt) { clickCount = 1; try { deepCopy((JLabel)evt.getSource()); } catch (Exception ex){} } } label1.addMouseListener(new MyMouseAdapter()); label2.addMouseListener(new MyMouseAdapter()); panel.setBorder(BorderFactory.createTitledBorder("Controllers")); getContentPane().add(panel,BorderLayout.SOUTH); centerPanel = new JPanel(); centerPanel.setBorder(BorderFactory.createTitledBorder(BorderFactory.createRaisedBevelBorder(),"Drawing Pad",TitledBorder.CENTER,TitledBorder.TOP)); centerPanel.setLayout(null); centerPanel.addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent evt) { if (clickCount == 1) { try { pasteLabel(evt.getX(),evt.getY()); } catch (Exception ex){} } } }); getContentPane().add(centerPanel); setSize(300,400); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setVisible(true); } public void deepCopy(JLabel label)throws Exception { baos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(baos); oos.writeObject(label); oos.close(); } public void pasteLabel(int x, int y)throws Exception { if (clickCount == 1) { bins = new ByteArrayInputStream(baos.toByteArray()); ObjectInputStream oins = new ObjectInputStream(bins); JLabel obj = (JLabel)oins.readObject(); centerPanel.add(obj); obj.setBounds(x,y,obj.getWidth(),obj.getHeight()); } } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { CopyLabel cl = new CopyLabel(); cl.createAndShowGUI(); } }); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
